Verify Board Support for the ASF Common Sensor Service.

The common sensor service requires board-specific configuration constants describing sensor devices, bus interfaces, I/O pin interfaces etc. for a particular hardware implementation. When a board is configured to provide the board hardware-specific details to the sensor service, the COMMON_SENSOR_PLATFORM configuration constant will be defined in the board-specific header file.
